New Taig Mill and Set up problems

[surrealism]

......

Hey Guys,
I finally bought and assembled the Deepgroove1.com mill, Running mach 3 and gecko 540

Set up went fine, (so I thought) and I started milling down some stock for my first project. I did not think to much of the motor travel being off, I just adjusted my 5 line g-code to mill the whole block.

So today I sit down to learn g-code a bit deeper, and code my first real paid project. As soon as I find my zeros, I move to the middle of the part.... It was not the middle.

OOOOO yea I forgot to set the stepper travel to my specific acme threads.....

I have now spend 6 hours trying to get these settings right (on my x axis... havent even tried y or z yet....)


Can someone walk me through the process for setting these? I have 2 right angle blocks, and a dial indicator, a metal precision 5in ruler.
What do I do?


also, shouldn't my inch per step number be the same as someone else who has the exact same package?

Thanks guys.... I am so tired of trying this on my own.

Yes, your steps per inch should be the same as everyone else with that setup. Unless you want to compensate for screw error, but I wouldn't bother at this point.

1.8deg per step, 360deg per rev, 1/10th micro-stepping, 20 turns per inch screw.

360/1.8 * 10 * 20 = 40,000

Thanks guys, and 40,000 seemed to be close enough to start some cuts.

I am now having some issue with feed rate....

If I call F3 vs. F1, there dosent seem to be a change...... mach shows it, but I am finding myself using the feed over-ride at 1-10 % of F3 value......

how can i set that up?

thanks

Well it turns out i am just a newbie.....

G01 +F* works....

I have lots to learn about the g code protocol.

Thanks for the help thus far.
